Quicksilver 808505T01 VST Electric Fuel Pump Kit for Mercury Outboard & MerCruiser

The Quicksilver 808505T01 VST Fuel Pump Kit is a genuine OEM replacement electric fuel pump kit designed for Mercury Marine EFI engines equipped with a Vapor Separator Tank (VST) assembly. As part of the Mercury Marine family, Quicksilver delivers factory-quality components engineered to exact OEM specifications for reliable marine fuel system performance.

This kit replaces the high-pressure electric fuel pump located inside the VST, which is responsible for delivering pressurized fuel directly to the engine's injectors. Proper fuel pressure and flow are critical for consistent EFI engine operation, making timely pump replacement an important part of marine engine maintenance.
